The sum of scott's age and greg's age is 33 years if greg's age is presented by g, scott's age represented by

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7

the answer is  

a.

4,624π mm2

step-by-step explanation:

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal

c) blue
